HANGER FOR LITTER-CARRIERS.

Specification of Letters Patent.

Application filed February 9, 1911. Serial No. 607,492.

of Illinois. have invented a new and useful Improvement in Hangers for L1tter-Car-- riers, of which the followlng 1s a specification.

l\I v.invention relates to certain new and useful improvements in hangers'for littercarriers. and fully described and ex plained in the specification and shown in- .the accompanying drawings. in which:

Figure l a side elevation showing my .improy'ed device and a portion of a littercarrier frame to which the same is attached;

Fig. 2 is an end view of the same; Fig. 3 is a section on the line 3 of Fig. 2, and Fig. 4 is a top'plan of a portion of track showing 1 curve therein with which the device is particularly adapted to cooperate. 7

Referring to the drawings. A is a portion of. a litter-carrier frame upon which is secured a bracket B. This bracket consists .of two side webs 7) which lie on opposite sides of the frame portion Agand which support between them a central b "as I) having on its lower face a notch F diametrically disposed across said face.

i .C a roller or grooved wheel adapted to run upon a track D which may be of the .flexible rod type. The wheel (1 is journaled'upon a pin at the upper end of a depending member E which extends downward beside the track and umlerneath-the same, having at its lower enda pin E which extends downward throughthe boss 5 and normal conditions the bead, by fitting inthe groove, will hold the wheel C. exactly in the plane of the track, so that there Will be.no accidental wabbling or twisting of the hanger upon its pivot upon the frame. It will be understood that such accidental twist- 7 ing of the hanger upon its pivotis-very undesirable because; feed and litter-carriers are,i n practice,- foreed out of the barn'with a single hard push and run, 'byreason of the momentum thus acquired across. the barn that their surfaces fit each yard to the dumping point, where they are automatically dumped and from which they are automatically returned by reason of the rise of the track when relieved of the load within the carrier.

At many times of the year the barn-yard is not a desirable place to walk in and it is therefore of great importance that a carrier be made so that it can readily be pushed to the dumping point by a single push delivered within the barn. Thus anything which would interfere with the free running of the carrier would be very undesirable becanseit might cause it to stop before it reached the dumping point or on its return before reaching. the barn. Now, any swiveling action between the frame and the hanger of a litter-carrier is most undesirable because it twists the ,wheel out of the planeof the track with the result that the track grinds on the flanges of the wheel so as to greatly interfere with the momentum of the carrier. The-present hanger is of such a type that the roller or wheel is held in perfect alinement at all times so that this grinding does not and cannot occur. On the other hand. it is necessary that. within the barn, where an extra push can readily-be imparted by the operator. the hanger should be free to swivel toa considerable extent in passing around cu1'v-essncl1 as the one shown in Fig. 4. It will be seen that in'the present device. while the pulley isyieldingly heldv 'in the proper position, it can by the ex ertion of proper force be turned upon its swivel. the amount of energy required for this purpose being determined by the depth of thegroove b and the bead fitting surface. aswell as the amount of material contained in the carrier. VViththis device, when a curve is reached the track will engage wi th the flanges of the pulleyexertmg a tw1st1ng pressure upon the swivel and manifestly turning the pulley; As soon as the carrler runs off the curve, the bead and groove will snap into complete registration and the pulley will again be held relatively firm in proper position.

I- realize that. considerable variation, is possible in the details of" the construction of the device wh-iclrIhave here set forth as the preferred form of, embodying my invention; -and I do not, therefore intend to limitfmyself to this specific form, my inn .tention 'being in the claims hereafter appendedto claim aiithe novel features disclosed in this construction as broadly as the state of the art will permit.

What I claim as new and desire to secure by Letters Patent is 1. In combination a frame, a bracket rigidly attached thereto, a hanger carrying a roller and swivelecl in the-bracket, and

interfitting erts on hanger and bracket for the purpose set forth.

2. in combination a frame, a bracket rigirlly attached thereto, a roller-carrying hanger, a pin thereon passing through :1

perforation in the bracket, a head on the pin, and an interfitting projection and depression on the adjacent faces of pin and bracket for the purpose set forth.

In testimony whereof I have hereunto set my hand and afiixed Iny seal'this 6th day -01 Feb, 1911.
